SHUTTLE FOR WEAVERS LOOMS.

SPECIFICATION forming part of Letters Patent No. 736,079, dated August11, 1903.

Application filed July 26, 1902. Serial No. 117,162. (No model.)

To all whom it may concern.-

Be it known that I, EDUARDO GOMES FER- REIRA, manufacturer, a citizen ofthe Republic of Brazil, residing at 83 Rua Primeiro de Marco, Rio de Janeiro, Brazil, have invented certain new and useful Improvements inShuttles for Veavers Looms, of which the following is a specification.

This invention relates to shuttles for weavers looms; and the object ofthe invention is to provide a simple deviceof this character which canbe easily threaded and from which the thread can be easily drawn duringthe weaving operation.

The invention is clearly shown in the accompanying drawings, forming apart of this specification, and in which Figure 1 is a longitudinalsectional elevation of a shuttle including my invention. Fig. 2 is aplan view of the same. Fig. 3 is an elevation of the head of theshuttle, taken from that side in which the eye thereof appears. Fig. 4is a transverse section taken in the line 4. 4:, Fig. 1; and Figs. 5 and6 are similar views taken in the lines 5 5 and 6 6, re-' spectively,Fig. 2.

Like characters refer to like parts in the several figures.

The numeral 1 indicates a channel or bore in head A of the shuttle,which is shown as being of approximately V-shaped form, the branches ofwhich converge toward the head of the shuttle and are located atopposite sides, respectively, of the axis thereof. One of the branchesof the channel or bore, or what might be considered the inner one, opensinto and leads from the chamber B, in which the bobbin 0 is removablymounted upon the usual spindle. The other branch of the channel or boreopens in the side of the shuttle at 3 to form an eye from which the weftof yarn or thread is drawn'from the bobbin by way of the approximatelyV- shaped channel or passage alluded to. A threading passage or slit yopens, respectively, into the channel or passage 1 and the top of theshuttle, it being of a shape to agree with that of said passage or bore,and the point at which the branches of said passage or slit converge isshown at 0. It will be seen that the walls of the inner branch on of theslit 1 are acute with respect to the top 6 of the shuttle, while at theinner end of the branch end of said passage or slit said walls are at anacute angle with respect to said top and gradually merge into a rightangle to said top, such latter disposition of the walls being at the eye3. The entering end of the slit or passage 3 is widened, as shown at s,and such branches where they converge are also widened, as at r, inorder to facilitatc the introduction of the thread or yarn into the boreor channel 1. The channel and threading-passage may, if desired, beformed in a separate piece H, which can be conveniently secured in thehead of the shuttle by means of screws 10, the part H being made of somelight metal, such as aluminium.

While it is not essential that the forward walls of the slit should bedisposed in the manner indicated, it is essential that the rear wallsthereof should be.

In use a portion of the thread is drawn from the bobbin 0 and theleading end thereof is placed in the upper portion of the slit 1 Bygrasping the free end of the yarn and pulling the same downward into theeye 3 the inclined walls of the slit Qfwill automatically and rapidlyguide the thread or yarn into the channel or passage 1.

Having described the invention, what I claim is- A shuttle having anapproximately V- shaped channel at one end thereof, the branches ofwhich converge toward the head of said shuttle, one of said branchesopening into the side of the shuttle to form an eye, and asimilarly-shaped threading-passage opening into the channel and top ofthe shuttle respectively, the rear wall of the inner branch of said slitbeing at an acute angle with respect to'the top of said shuttle and thecorresponding wall of the other branch of said slit being initially atan acute angle with respect to said top and merging gradually into aright angle relatively to said top.

Intestimony whereof I have hereunto set my hand in presence oftwosubscribing witnesses.

EDUARDO GOMES FERREIRA.
